Abstract
PURPOSE Portal vein and superior mesenteric vein thrombosis (PVT/SMVT) are potentially morbid complications of radiation dose-escalated local therapy for pancreatic cancer. We retrospectively reviewed records for patients treated with and without intraoperative radiation (IORT) to identify risk factors for PVT/SMVT. METHODS Ninety-six patients with locally advanced or borderline resectable pancreatic adenocarcinoma received neoadjuvant therapy followed by surgical exploration from 2009 to 2014. Patients at risk for close or positive surgical margins received IORT boost to a biologically effective dose (BED10) > 100. Prognostic factors for PVT/SMVT were evaluated using competing risks regression. RESULTS Median follow-up was 79 months for surviving patients. Fifty-six patients (58%) received IORT. Twenty-nine patients (30%) developed PVT/SMVT at a median time of 18 months. On univariate competing risks regression, operative blood loss and venous repair with a vascular interposition graft, but not IORT dose escalation or diabetes history, were significantly associated with PVT/SMVT. The development of thrombosis in the absence of recurrence was significantly associated with a longstanding diabetes history, post-neoadjuvant treatment CA19-9, and operative blood loss. All 4 patients who underwent both IORT and vascular repair with a graft developed PVT/SMVT. PVT/SMVT in the absence of recurrence is not associated with significantly worsened overall survival but led to frequent medical interventions. CONCLUSIONS Approximately 30% of patients who underwent neoadjuvant chemoradiation for PDAC developed PVT/SMVT a median of 18 months following surgery. This was significantly associated with venous reconstruction with vascular grafts, but not with escalating radiation dose. PVT/SMVT in the absence of recurrence was associated with significant morbidity.

Abstract
Background & Aims We aimed to evaluate the impact of oesophageal varices (OV) and their evolution on the risk of complications of compensated advanced chronic liver disease (cACLD) caused by non-alcoholic fatty liver disease (NAFLD). We also assessed the accuracy of non-invasive scores for predicting the development of complications and for identifying patients at low risk of high-risk OV. Methods We performed a retrospective assessment of 629 patients with NAFLD-related cACLD who had baseline and follow-up oesophagogastroduodenoscopy and clinical follow-up to record decompensation, portal vein thrombosis (PVT), and hepatocellular carcinoma. Results Small and large OV were observed at baseline in 30 and 15.9% of patients, respectively. The 4-year incidence of OV from absence at baseline, and that of progression from small to large OV were 16.3 and 22.4%, respectively. Diabetes and a ≥5% increase in BMI were associated with OV progression. Multivariate Cox regression revealed that small (hazard ratio [HR] 2.24, 95% CI 1.47-3.41) and large (HR 3.86, 95% CI 2.34-6.39) OV were independently associated with decompensation. When considering OV status and trajectories, small (HR 2.65, 95% CI 1.39-5.05) and large (HR 4.90, 95% CI 2.49-9.63) OV at baseline and/or follow-up were independently associated with decompensation compared with the absence of OV at baseline and/or follow-up. The presence of either small (HR 2.8, 95% CI 1.16-6.74) or large (HR 5.29, 95% CI 1.96-14.2) OV was also independently associated with incident PVT. Conclusion In NAFLD-related cACLD, the presence, severity, and evolution of OV stratify the risk of developing decompensation and PVT. Impact and implications Portal hypertension is the main driver of liver decompensation in chronic liver diseases, and its non-invasive markers can help risk prediction. The presence, severity, and progression of oesophageal varices stratify the risk of complications of non-alcoholic fatty liver disease. Easily obtainable laboratory values and liver stiffness measurement can identify patients at low risk for whom endoscopy may be withheld, and can also stratify the risk of liver-related complications.

Abstract
BACKGROUND Portal vein thrombosis is a fairly common and potentially life-threatening complication in patients with liver cirrhosis. The risk factors for portal vein thrombosis in these patients are still not fully understood. OBJECTIVES This study aimed to investigate the associations between various risk factors in cirrhotic patients and the development of portal vein thrombosis. PATIENTS AND METHODS In this case-control study performed at the Shiraz organ transplantation center, Iran, we studied 219 patients (> 18 years old) with liver cirrhosis, who were awaiting liver transplants in our unit, from November 2010 to May 2011. The patients were evaluated by history, physical examination, and laboratory tests, including factor V Leiden, prothrombin gene mutation, Janus Kinase 2 (JAK2) mutation, and serum levels of protein C, protein S, antithrombin III, homocysteine, factor VIII, and anticardiolipin antibodies. RESULTS There was no statistically significant difference in the assessed hypercoagulable states between patients with or without portal vein thrombosis. A history of previous variceal bleeding with subsequent endoscopic treatment in patients with portal vein thrombosis was significantly higher than in those without it (P = 0.013, OR: 2.526, 95% CI: 1.200 - 5.317). CONCLUSIONS In our population of cirrhotic patients, treatment of variceal bleeding predisposed the patients to portal vein thrombosis, but hypercoagulable disorders by themselves were not associated with portal vein thrombosis.

Abstract
BACKGROUND & AIMS Portal vein thrombosis (PVT) is common in patients with cirrhosis and may have adverse clinical consequences. We investigated whether PVT is associated with survival in patients with cirrhosis. METHODS Using the United Network for Organ Sharing registries from 2002 through 2013, we followed a cohort of transplant-naive adults with cirrhosis without hepatocellular carcinoma (N = 66,506) from the time of transplant listing until the time of liver transplantation or death before transplantation. We used Cox proportional hazards analysis and competing risks analysis to compare patients who had PVT at the time of listing (n = 2207) with those who did not (n = 64,299) with regard to the risk of transplantation or death before transplantation, after adjusting for important baseline characteristics. RESULTS During a mean follow-up period of 1.78 years, 17,757 (27%) patients died before liver transplantation, 29,179 (44%) patients underwent transplantation, and 19,570 (29%) patients were still alive without having undergone transplantation. Compared with patients who did not have PVT, patients with PVT had lower mortality (adjusted hazard ratio [AHR], 0.88; 95% confidence interval [CI], 0.81-0.96), a similar risk of transplantation (AHR, 0.95; 95% CI, 0.89-1.02), and a lower risk of the combined outcome of death or transplantation (AHR, 0.92; 95% CI, 0.88-0.97). Similar results were found by competing risks analyses. Independent predictors of mortality included age, model for end-stage liver disease score, serum albumin level, ascites, encephalopathy, diabetes, hepatitis C virus infection, and low body mass index (<24.4 kg/m(2)). CONCLUSIONS Among patients with cirrhosis on liver transplant waiting lists, patients with PVT have lower mortality than patients without PVT.

Abstract
The coagulation pattern and the determinants of portal vein thrombosis (PVT), both in patients with and without cirrhosis, are still largely unknown. The aim of this study was to evaluate whole blood thromboelastometry profile, performed by ROTEM®, of both cirrhotic and non-cirrhotic subjects with PVT. Two different groups were considered: i) 14 non-cirrhotic PVT patients, ii) 35 cirrhotic patients with PVT. Controls were sex- and age-matched healthy volunteers and cirrhotic subjects without PVT, respectively. ROTEM® assays (i.e. INTEM, EXTEM, NATEM, and FIBTEM) and traditional coagulative parameters (i.e. platelet count, PT/INR, aPTT, and fibrinogen) were performed on blood samples from each subject. There were no significant differences in ROTEM® profile, as for INTEM, EXTEM, and NATEM assays, and in traditional coagulative parameters, between PVT patients, both with and without cirrhosis, and control groups. Interestingly, Maximum Clot Firmness (MCF) in FIBTEM was significantly higher in non-cirrhotic PVT patients (19 mm) than in healthy volunteers (11 mm, p<0.05). The amplitude of MCF in FIBTEM revealed to be a useful tool to discriminate non-cirrhotic subjects with PVT from those without thrombotic events. Larger prospective studies are needed to evaluate the relevance of the association between the alterations of ROTEM® profiles and PVT in cirrhotic patients.

Abstract
BACKGROUND AND PURPOSE To investigate the feasibility of direct magnetic resonance portal vein thrombosis (PVT) visualization with T2*-weighted imaging (T2*WI) without contrast agent. METHODS Thirty patients with PVT were included in this study. All of them were imaged with contrast-enhanced CT (CE-CT) as well as non-contrast MRI T1, T2 and T2*WI. Imaging data was independently analyzed by two experienced radiologists. T2*WI of all PVT was compared slice-by-slice with each of the comparison sequences (T1WI, T2WI and CE-CT) on the following categories: the location, size, boundary, and conspicuity of thrombus and portal veins. RESULTS The average score of PVT visualization in T2*WI was higher than T1WI and T2WI in location, size, boundary and conspicuity (t = 7.54 - 84.16, P<0.05), and higher than CE-CT in boundary and conspicuity (t = 3.03- 6.98, P<0.05). For portal vein visualization, there was no significant score difference in left, middle and right portal veins between CE-CT and T2*WI (t = -1.76- 1.35, P>0.05). CONCLUSIONS Our results suggest T2*WI can characterize PVT accurately with high quality without the use of intravenous contrast agents.

Abstract
Thrombophilia is a rare but potentially catastrophic phenomenon occurring in patients having tendency of thrombosis. It may lead to serious complications. The etiology of thrombophilia is thought to be multifactorial and related to both acquired and inherited factors. Inflammatory bowel disease is an acquired cause of thrombophilia. Thromboembolic events are seen during inflammatory bowel disease, especially during the active period of the disease. In inflammatory bowel disease, thrombus formation in portal, splenic and mesenteric veins are not common. Besides, the association of genetic disorders related to metabolism of homocysteine with inflammatory bowel disease has been evidenced, especially in Crohn disease and rarely in ulcerative colitis. We present a rare case of ulcerative colitis in association with combined portal, splenic and mesenteric vein thrombosis. The patient was recently diagnosed with the disease which was in the inactive period. Interestingly, our patient was also heterozygous for the mutation in methylenetetrahydrofolate reductase (MTHFR) gene.
